Linux endpoint shown in "About Roon" but missing from "Audio Setup" [self-resolved]

Hi all, running Roon 1.3 on a Mac, connecting to endpoints on a pair of Beaglebone Blacks in different rooms, each connected to a Schiit DAC.

They both appear if I click on “About Roon”, which shows this:

But when I go to audio setup, only one of them appears:

The machine that is missing here can play audio via mpd: it is on the network and attached to my NAS and talking to my DAC. It seems that Roon just isn’t seeing it properly.

Any ideas here?

Thanks!

Justin

Solved… somehow. I removed X from the Bone, rebooted, and then it became visible (I’d tried rebooting before removing X, for whatever that is worth).
